“A speck of carfentanil the size of a grain of sand can kill you,” said U.S. Attorney Adam Braverman in a written release.

Agents also found sheets of fentanyl gel tablets in Gornik's home numbering 100 tabs per sheet that Gornik purchased from another darknet vendor based in Oklahoma. That vendor has also pleaded guilty to distribution of fentanyl and is awaiting sentencing.

A notebook with USPS tracking numbers and pay/owe sheets along with rolls of labels for printing were also found in the search of Gornik’s Clairemont home.
